Yes, but to be on the safe side you should patch your wii with priiloader 3.0 and put on some system hacks.
(wiibrew.org)
Download priiloader, put it in the SD card.
Create the hacks.ini (tutorial on wiibrew.org)
Turn on no disc update, to make sure NOBODY updates your wii (no matter what version you have, I heard it won't be too long untill nintendo blocks ANY mods).
Turn on some more hacks if you want to, but not needed.
